v03ai – Google Veo 3-powered vertical AI video generator (TikTok/IG-ready)

Hi HN! We’ve built V03 AI – the first AI video generator leveraging Google Veo 3 to create vertically formatted videos for TikTok/Instagram with native audio sync.

The problem:
Current AI video tools (Runway, Pika) require manual cropping for vertical formats, struggle with physics-based realism, and lack integrated audio. For social creators, reformatting 16:9 videos wastes 30%+ creative time.

How V03 AI solves this:
• Vertical-first workflow: Native 9:16 aspect ratio support (no cropping)

• Cinematic physics: Veo 3-powered lighting/motion realism (see shattered glass demo)

• Audio-video sync: Auto-generates SFX, dialogue & ambient sound

• <60s generation: 8s clips in 4K (tested on Pro tier)

• Cost efficiency: 0.5/video (vs. 5+ competitors)

Technical highlights:
→ Google Veo 3 API integration (quality/fast modes)
→ Hardware-optimized rendering (tested on M2 Ultra & cloud instances)
→ Dynamic prompt interpretation (e.g., "slow-motion glass shatter with hyper-reflections")
